Description

Technical Field

[0001] This invention relates to the field of automotive parts assembly, specifically a bolt mounter for assembling automotive limiter brackets. Background Technology

[0002] Limiters are a common type of automotive component, often used to connect car doors to the car body. When installing limiter brackets, bolts are usually required for connection. However, traditional assembly requires manual removal of the bolts and then insertion into the corresponding bolt holes on the limiter bracket for screwing, which is quite laborious.

[0003] In the prior art, for example, the utility model patent with application number CN212300777U proposes an adjustable connection structure for a limiter impact test bench, although it discloses the following connection method and installation structure of the limiter bracket:

[0004] The limiter bracket is bolted to the door connection end and the body connection end respectively. The positional relationship between the door connection end, the body connection end and the limiter bracket can be adjusted by changing the position of the bolt in the slide groove of the plate component. The limiter bracket is also provided with screw holes.

[0005] However, the specifics of the installation process and how to connect the bolts during assembly were not disclosed in the plan. Summary of the Invention

[0006] In order to overcome the laboriousness of bolt connections during the installation of limiter brackets, this invention proposes a bolt installer for assembling automotive limiter brackets.

[0007] The technical problem to be solved by this invention is achieved by the following technical solution:

[0008] A bolt installer for assembling automotive limiter brackets includes a main mounting base with a storage device and an auxiliary installation device mounted on it. The storage device includes a long storage cylinder mounted on the main mounting base. The upper end of the long storage cylinder is open, and the cylinder is used to store and supply new bolts. The auxiliary installation device is used to extract the new bolts and move them to a specific position for installation.

[0009] As a further improvement of the present invention, the auxiliary installation device includes a mounting frame mounted on a main mounting base and a transport assembly mounted on the mounting frame. The transport assembly is coupled with a lifting assembly. The lifting assembly is connected to a main turntable, and a rotary drive assembly is mounted on the lower part of the main turntable. The rotary drive assembly is connected to a final clamping device. The transport assembly is used to transport the extracted new bolt. The lifting assembly is used to lift the new bolt to facilitate resetting and installation. The rotary drive assembly is used for tightening the new bolt during installation. The final clamping device is used to secure the new bolt.

[0010] As a further improvement of the present invention, a spring is installed at the bottom of the inner side of the storage cylinder, and the spring is connected to an upward push plate that can slide vertically along the inner side of the storage cylinder. The novel bolts can be stacked and stored inside the storage cylinder.

[0011] As a further improvement of the present invention, two L-shaped baffles are welded to the upper end of the storage cylinder, and a discharge chute is provided at the upper right end of the storage cylinder. By means of spring force, the uppermost novel bolt can be made to abut against the two baffles, and the novel bolt must pass through the discharge chute to enter and exit the storage cylinder.

[0012] As a further improvement of the present invention, the transport assembly includes an I-type motor mounted on a mounting frame, a lead screw connected to the I-type motor, a mounting plate connected to the lead screw, and a guide rail mounted on the mounting frame; the mounting plate and the guide rail are in sliding engagement. The lead screw is mounted on the mounting frame via bearings. That is, the horizontal movement of the mounting plate and the subsequently fixed novel bolts can be controlled by the lead screw nut transmission.

[0013] As a further improvement of the present invention, the lifting assembly consists of hydraulic cylinders and I-shaped guide rods, both installed at the lower end of the upper plate; the hydraulic cylinders are connected to the main turntable, and the I-shaped guide rods are slidably connected to the main turntable. That is, the hydraulic cylinders can drive the main turntable and the subsequently fixed new type of bolts to lift and lower.

[0014] As a further improvement of the present invention, the rotary drive assembly consists of a Type II motor installed at the lower center of the main turntable, a rotating rod connected to the Type II motor, and a longitudinal suspension rod connected to the rotating rod. That is, the Type II motor can drive the longitudinal suspension rod and the subsequently fixed novel bolts to rotate.

[0015] As a further improvement of the present invention, an annular groove is provided at the bottom of the main turntable for slidingly mounting the longitudinal hanger. The annular groove is a dovetail groove, which serves to guide and support the longitudinal hanger.

[0016] As a further improvement of the present invention, the overall clamping device includes a reference plate connected to the lower end of the longitudinal lifting rod and a semi-circular clamping block fixedly connected to the reference plate; the front right end and the rear right end of the semi-circular clamping block are provided with inner arc grooves, and an arc-shaped telescopic clamping block is slidably installed in each inner arc groove. The two arc-shaped telescopic clamping blocks can extend out of the inner arc grooves and cooperate with the semi-circular clamping block, and fit around the recessed part of the bolt head of the new type of bolt to facilitate the extraction of the new type of bolt.

[0017] As a further improvement of the present invention, the overall clamping device also includes a cylinder mounted on a reference plate and a type II guide rod; a U-shaped block connected to the cylinder is slidably mounted on the type II guide rod, and a pressing rod is mounted on the middle right side of the U-shaped block. When the cylinder pushes the pressing rod, the pressing rod can press the bolt head to the right.

[0018] As a further improvement of the present invention, the front and rear parts of the U-shaped block are provided with straight grooves, and each arc-shaped telescopic clamping block is welded with a relief rod, the upper end of each relief rod slidingly engaging with the straight groove. That is, by pushing with a cylinder, the two arc-shaped telescopic clamping blocks can slide to the right and extend out of the inner arc groove, and after being pushed to a certain extent, the pressing rod can engage with the two arc-shaped telescopic clamping blocks to clamp and fix the bolt head.

[0019] The beneficial effects of this invention are:

[0020] This invention enables the automatic supply of new bolts and facilitates their automatic extraction and transport to the assembly point for easy assembly. It can also automatically screw the new bolts into the specified threaded holes on the limiter bracket, saving manpower and enabling continuous automatic installation of new bolts for mass assembly.

The upper end of the long storage cylinder 2 is open, and the long storage cylinder 2 is used to store and supply new bolts. The auxiliary installation device is used to extract the new bolts and move them to a specific position for installation.

[0032] like Figure 2 As shown, the auxiliary installation device includes a mounting frame 6 mounted on the main mounting base 1 and a transport assembly mounted on the mounting frame 6. The transport assembly is equipped with a lifting assembly. The lifting assembly is connected to a main turntable 7, and a rotary drive assembly is mounted on the lower part of the main turntable 7. The rotary drive assembly is connected to a final clamping device. The transport assembly is used to transport the extracted new bolts. The lifting assembly is used to lift the new bolts to facilitate resetting and installation. The rotary drive assembly is used for tightening the new bolts during installation. The final clamping device is used to secure the new bolts.

[0033] like Figure 4 and Figure 5 As shown, a spring 3 is installed at the bottom of the inner side of the storage cylinder 2, and the spring 3 is connected to an upper push plate 4 that can slide vertically along the inner side of the storage cylinder 2. The inner side of the storage cylinder 2 can be used to stack and store new bolts.

[0034] like Figure 2 As shown, two L-shaped baffles 5 are welded to the upper end of the storage cylinder 2, and a discharge chute 2a is provided on the upper right end of the storage cylinder 2. By means of the elastic force of the spring 3, the uppermost new type bolt can be made to abut against the two baffles 5, and the new type bolt must pass through the discharge chute 2a to enter and exit the storage cylinder 2.

[0035] like Figure 2 and Figure 3 As shown, the transport assembly includes an I-type motor 11 mounted on a mounting frame 6, a lead screw 8 connected to the I-type motor 11, a mounting plate 9 connected to the lead screw 8, and a guide rail 10 mounted on the mounting frame 6; the mounting plate 9 and the guide rail 10 are in sliding engagement. The lead screw 8 is mounted on the mounting frame 6 via bearings. That is, the horizontal movement of the mounting plate 9 and the subsequently fixed new bolts can be controlled by the lead screw nut transmission.

[0036] like Figure 2 and Figure 3 As shown, the lifting assembly consists of hydraulic cylinders 12 and I-shaped guide rods 13, both installed at the lower end of the upper plate 9. The hydraulic cylinders 12 are connected to the main turntable 7, and the I-shaped guide rods 13 are slidably connected to the main turntable 7. That is, the hydraulic cylinders 12 can drive the main turntable 7 and the subsequently fixed new bolts to lift and lower.

[0037] like Figure 6 As shown, the rotary drive assembly consists of a Type II motor 14 installed at the lower center of the main turntable 7, a rotating rod 15 connected to the Type II motor 14, and a longitudinal suspension rod 16 connected to the rotating rod 15. That is, the Type II motor 14 can drive the longitudinal suspension rod 16 and the subsequently fixed new bolts to rotate.

[0038] like Figure 6 As shown, the bottom of the main turntable 7 has an annular groove 7a for slidingly mounting the longitudinal hanger 16. The annular groove 7a is a dovetail groove, which serves to guide and support the longitudinal hanger 16.

[0039] like Figure 2 , Figure 6 as well as Figure 7 As shown, the overall clamping device includes a reference plate 17 connected to the lower end of the longitudinal lifting rod 16 and a semi-circular clamping block 18 fixedly connected to the reference plate 17. The semi-circular clamping block 18 has an inner arc groove 18a at both its front right end and rear right end, and an arc-shaped telescopic clamping block 19 is slidably installed in each inner arc groove 18a. The two arc-shaped telescopic clamping blocks 19 can extend out of the inner arc groove 18a and cooperate with the semi-circular clamping block 18, fitting around the recessed portion of the bolt head of the new type of bolt to facilitate its extraction.

[0040] like Figure 7As shown, the overall clamping device also includes a cylinder 20 mounted on the reference plate 17 and a type II guide rod 21; a U-shaped block 22 connected to the cylinder 20 is slidably mounted on the type II guide rod 21, and a pressing rod 24 is mounted on the middle right side of the U-shaped block 22. When the cylinder 20 pushes the pressing rod 24, the pressing rod 24 can press the bolt head to the right.

[0041] like Figure 7 As shown, the U-shaped block 22 has straight grooves 22a at both the front and rear. Each arc-shaped telescopic clamp 19 is welded with a relief rod 23, and the upper end of each relief rod 23 slides into the straight groove 22a. That is, by pushing the cylinder 20, the two arc-shaped telescopic clamps 19 can slide to the right and extend out of the inner arc groove 18a. After being pushed to a certain extent, the pressing rod 24 can press against the two arc-shaped telescopic clamps 19 to clamp and fix the bolt head.

[0042] Before using this invention, it is necessary to prepare the following: Figure 1 The novel bolts shown are stacked one by one inside the storage cylinder 2 with the bolt head facing upwards and the threaded portion facing upwards, so that the bolt head of the uppermost novel bolt abuts against the two blocking plates 5. The invention is then placed to the left of the limiter bracket assembly point.

[0043] First, the lead screw 8 is driven to rotate by the type I motor 11, which drives the overall clamping device to move horizontally to the right until the central arc surface of the semi-circular clamping block 18 abuts against the recessed part of the bolt head of the uppermost new bolt.

[0044] Furthermore, by pushing the U-shaped block 22 to the right by the cylinder 20, the two arc-shaped telescopic clamping blocks 19 first slide to the right in an arc shape to lock the recessed part of the bolt head of the new type of bolt again. Then, the pressing rod 24 moves to the right to cooperate with the two arc-shaped telescopic clamping blocks to clamp and fix the bolt head of the new type of bolt.

[0045] Furthermore, the type I motor 11 continues to drive the lead screw 8 to rotate, causing the clamped new bolt to be moved away from the inside of the storage cylinder 2 and transported to the top of the threaded hole of the designated limiter bracket.

[0046] Furthermore, while the hydraulic cylinder 12 pushes down the main turntable 7, the type II motor 14 drives the rotating rod 15 to rotate, so that the clamped and fixed bolts are screwed down into the corresponding threaded holes to complete the connection and assembly.

[0047] Finally, cylinder 20 pulls the U-shaped block 22 to the left to release the fixing of the newly installed bolts. Then, following the above method, the main clamping device is controlled to first rise, then move to the left, and finally fall to reset.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
